Abstract

The invention relates to a prefabricated sandwich thermal-insulation laminated wallboard. The wallboard is characterized by comprising an inner prefabricated wallboard, an outer prefabricated wallboard, a thermal-insulation layer (2) located between the inner prefabricated wallboard and the outer prefabricated wallboard, and a thermal-insulation connecting piece, wherein the inner prefabricated wallboard and the outer prefabricated wallboard are poured with longitudinal and transverse tensioned bar plane frames as skeletons; the thermal-insulation connecting piece passes through the inner prefabricated wallboard, the outer prefabricated wallboard and the thermal-insulation layer (2) in an embedded way; and the thermal-insulation layer (2) is a foamed thermal-insulation material and is poured between the inner prefabricated wallboard and the outer prefabricated wallboard. According to the invention, the thermal-insulation material overcomes the shortcomings of great needs of labor and low automation degree of the traditional prefabricated sandwich thermal-insulation wallboards through one-shot injection in a factory and adequate filling and compacting of a cavity in virtue of physical and chemical changes of the material; meanwhile, the thermal-insulation material and the contact surface of the inner and outer prefabricated wallboards are effectively bonded together, so rain water is prevented from intruding through gaps produced by stripping of the inner and outer prefabricated wallboards and is thus prevented from influencing the thermal insulation effect of the thermal insulation layer.

Example Embodiment

[0044] The present invention will be further described below in conjunction with the drawings and specific embodiments.
[0045] See Figure 3-Figure 11 , A prefabricated sandwich thermal insulation laminated wall panel, comprising inner and outer prefabricated wall panels, an insulation layer 2 located between the two, and thermal insulation connectors; the inner and outer prefabricated wall panels are longitudinally and laterally stressed The plane grid is cast as a skeleton; the thermal insulation connector is embedded through the inner and outer prefabricated wall panels and the thermal insulation layer 2; the thermal insulation layer 2 is a foamed thermal insulation material and is cast on the inner and outer layers Between prefabricated wall panels.
[0046] The thermal insulation layer 2 is any one of foam thermal insulation materials such as polyurethane, phenolic, foamed cement, foamed glass, and polystyrene resin.
[0047] The thickness of the thermal insulation layer 2 is 30-200 mm.
[0048] See Figure 4 The thermal insulation connector is made of stainless steel and includes a truss connector 1 and a reinforcement member 3. The truss connector 1 and the reinforcement member 3 are embedded through the inner and outer prefabricated wall panels and the thermal insulation layer 2 .
[0049] See Figure 5 The truss connector 1 is a single-piece truss connector or a two-piece truss connector.
[0050] The reinforcing member 3 is one or more of a sleeve reinforcing member, a flat reinforcing member, a pin reinforcing member, and a pin connecting member, and the reinforcing member 3 functions as a wallboard reinforcement.
[0051] See Figure 3-Figure 11 , A method for manufacturing the above-mentioned prefabricated sandwich thermal insulation laminated wallboard includes the following steps to prevent the foaming material from leaking from the gap between the side mold and the precast concrete;
[0052] E) Injecting thermal insulation material: A pressure injection machine is used to inject the foam thermal insulation material into the cavity, and the entire cavity is filled by the weight and physical and chemical changes of the foam thermal insulation material.
[0053] See Figure 7-Figure 11 The side mold includes a lower magnetic side mold and an upper magnetic side mold; the lower magnetic side mold includes a lower side mold 4b and a magnetic fixing bolt, and the upper magnetic side mold includes an upper side mold 4a, a magnetic fixing bolt, and a fixed Iron parts, hard filler material 4d, flexible material 4c; the upper side mold 4a, lower side mold 4b are stainless steel materials; the hard filler material 4d is one of wood and hard plastic; the flexible material 4c is One of polyurethane, polystyrene board, rubber, etc.
[0054] The thermal insulation board of the present invention does not require FRP thermal insulation connectors, does not require manual participation during production, reduces labor intensity, and improves production efficiency; avoids the problem of easy damage to thermal insulation panels when FRP thermal insulation connectors are used, and improves the yield; when concrete is poured first Pouring the inner and outer prefabricated wall panels, and then pouring the insulation layer, without using the insulation board as the core mold, the pouring process is simple, the production reliability is high, and the product quality is improved; the insulation layer and the prefabricated laminated wall panel are fixed by the insulation connector, and The insulation layer is closely integrated with the contact surface of the inner and outer prefabricated wall panels, which can effectively avoid the separation of the two; through the automated assembly line, the production efficiency of the prefabricated sandwich insulation wall panels can be improved, and the product quality of the thermal insulation prefabricated sandwich insulation wall panels; stainless steel insulation connectors are used , On the one hand, it can avoid the generation of cold and hot bridges of wall panels, on the other hand, it enhances the integrity of prefabricated wall panels and eliminates potential safety hazards.
[0055] The thermal insulation material of the present invention passes through a one-time injection process in the factory and uses its own physical and chemical changes to fully fill the dense cavity, which changes the disadvantages of traditional prefabricated sandwich thermal insulation wall panels that require a large amount of labor and low automation. At the same time, the thermal insulation material is effectively combined with the contact surface of the internal and external prefabricated wallboards to avoid the gap between the two caused by peeling and causing rainwater to invade and affect the thermal insulation effect of the thermal insulation layer. The production process of the prefabricated sandwich thermal insulation laminated wallboard is strictly controlled, and the quality of the products produced is stable and reliable. It can solve the problems of traditional construction site material waste and environmental pollution. It reflects the transformation of my country's construction industry to industrialization and industrialization. A major change to traditional building insulation design and construction methods is an effective way to solve the quality and safety problems and fire prevention problems of building external insulation projects.
